Any ideas why it is not working ? via app or via browser using my mobile it does work too. It kinda shows to me that the issue is not the WIFI since they are all at the same wifi.

They are on the same subnet.

No, I toggling another device, the primary that is connect to the lamp itself.

Hi

I have two Shelly 2.5, one of them connected to a light and the other acting as virtual parallel switch. It was working fine until somedays ago.

I have at the virtual parallel switch, at the Button switched ON url the following URL http://10.2.2.5/relay/0?turn=toggle. The same goes for the Button switched Off url. When I toggle the switch physically or via the app, it doesn't turn on or off. If I use a browser URL and use the same command it does work.

The wifi seems fine since I can access both devices via browser or app. Both devices are with the latest firmware 20221027-092056/v1.12.1-ga9117d3

Any ideia why it is not working ?

Ok. I gave up to understand how I created the quadro_geral topic. I went back to use the deviceid.

Thanks

Hi

I have two EM devices. The first one I copied a MQTT flow for node red. It works very well.

The second one is giving me a hard time. In all honesty I don't recall how I create a topic that is different than the device id. It's Shellies/quadro_geral/# . If I change the topic for something different it doesn't as is expected.

The problem is how to add the second one ? I can copy and past the first flow, but I can't find where the name of the topic was created and how I can differentiate the second one from the first.

It's probably a very dumb question from a newbie, but I'm really struggling

Thanks

Adding more information.

I checked the power at the SW1 and O1. Both are always with load 110v at each.

I tried detached, toggle switch, edge switch and the result is the same all with power. I assume one should be neutral (O1) and the other only on if the web interface says on.

I double check the wiring at the input side, N has no power and L has power.

Really lost here.

Hi all

I have a Shelly 2.5 which it's connect to power. I can access it via WIFI, I can see at the device info that it is receiving around 110v. If I switch to on SW1 or SW2 (tried both), I can measure that there is 110v at the SW connector. Nevertheless, the lamp doesn't turn on.

Just one more information, the lamp is directly connected to Shelly, there is no mechanical/standard switch in between.

The lamp is connected to the O1 and SW1 or O2 and SW2

If I connect the lamp directly it works flawless

Any ideas ?

Thanks for your reply.

I just bought the Shelly 2.5. I thought it will work with most of my things and it has power measurement. This is the only case I have for 220v. It has a motor that pressurizes the water. It turns on every time a faucet is open, but in the quiet of the night having it turning on and off is kind of annoying, so I turn it off at 11:00 pm and on at 7:00am.

Since I have sonoff basic R2 and it handles 10A, I guess 10A is what it needs. I don't have the specs of the motor.

About the power... Yes, in my country (Brazil) when you have 220v typically you would need to phases coming on both wires, so you have to add 2 x 110v. Regarding powering it off... some devices might still work, but with less potency, it can also break the device. I don't have a problem if I had to switch off both at the same time.

One thought that just occurred me is maybe I can join both 110v cable at one L input, use one O as output for two cables that goes to each pole of the outlet. The issue is the neutral.... And both wires together may cause a short circuit.

I'm by no means a electrician or electrical engineer, I'm just a curious homeowner...

Hi,

How do I connect Shelly 2.5 in a two phase 110v resulting in 220v ? It' a relay for a power outlet that expects 110v coming also on both wires going to it.

I thought of connecting both to the both L connector and the output to 01 and 02. There is no neutral in this case.

Issues that I foresee:To turn it on, I'll have to turn on both switches at the same time

To measure the power usage I'll have to sum both relays.

Am I doing it right or is there an easy way ?

Nowadays I use a Sonoff R2 Basic. For it I just connected each wire to input and two to the output, no neutral need in this case since both carry power. I want to change it to be able to also measure power usage of that outlet

Thanks for any input
